The Effect of Water and Food Restriction on Physiological Functional Traits Lori-Bakhtiari Lambs Their Crosses
This study was conducted to compare the feedlot performance and growth traits of Lori-Bakhtiari (n=39), Romanov × Lori-Bakhtiari (n=38) and Pakistani × Lori-Bakhtiari crossbred (n=12) lambs during two consecutive years. Lambs were weaned at the age of 90 ± 5 days. After weaning and preliminary fattening period, three groups of lambs were fattened for 90 days in the same conditions. The resul...
In a survey of 430 Lori-Bakhtiari sheep at a slaughterhouse in Iran, gallstones were found in the gallbladder of 7 sheep (1.6%). Biliary calculi were more frequent in adult and female sheep (P < 0.05). Chemical analysis of the gallstones revealed 6 sheep with pigment (bilirubin) stones and 1 sheep with cholesterol stones. Chemical composition of bile in these sheep was evaluated. Bacteriologic ...
Background The presence of different missense mutations in sheep breeds have shown that the bone morphogenetic protein receptor 1B (BMPR1B), bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) genes play a vital role in ovulation rate and prolificacy in ewes. Therefore, the present study aims to investigate BMPR1B, BMP15 and GDF9 gene mutations in prolific ewes of I...
The purpose of this study was evaluation of leptin gene polymorphism by PCR-SSCP and its relationship with some growth traits in Lori Bakhtiari and crossbred of Lori Bakhtiari- Afshari sheep. Blood samples were collected from 58 sheep (male and female) of Lori-Bakhtiari in Shahr-e-Kord Sholi station and 42 sheep (male and female) of Lori Bakhtiari-Afshari crossbreed from villages of Shahr-...
